Application filed August 14, 1918. Serial No. 249,768,

To all whom it may concern:

be it known that 1, Oscar IIAYES, a citizen of the United States, residing at Denver, in the coiiinty'of Denver and State of Colorado, have invented certain new and usefui improvements in Valve-Control Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improved air control device, and more particularly to a device of this character adapted to be operatively connected to theintake manifold of internal combustion engines for motor driven vehicles, whereby to add to thegaseous mixture as admitted to or passing through, the manifold, an additional supply of air, and which said supply may be conveniently and accurately regulated or entirely shut off at will.

It is a matter of common knowledge that when an engine is cold, as'on starting, a richer mixture is desirable, whereas after the engine becomes heated far'better results are obtainable, to say nothin of the saving of gas, by a lighter mixture, and with this in view compensating valves of various types and designs have hereto-fore been'extensively employed to regulate the gaseous mixture after it has left the carburetor by adding to said mixture a direct supply of air. Most of these prior constructions with which I am familiar have proven satisfactory for their intended purposes to a large extent, but it has been ascertained in practice that after some considerable use, especially when pivotally connected parts are relied upon, the parts tend to become bent, broken, dislocated, or will stick, withthe result that they fail to function properly. and it is one of the objects of the present invention to provide a compensating valve more positive and direct in operation, than prior similar valves, and otherwise overcoming existing difficulties and defectsyand at the same time making possible a-valve of the type under consideration neat in design and construction, including a -minimum number of parts and hence simple and cheap to produce, while at the same time highly efiicient and satisfactory in use.

In carrying out the invention it is proposed to provide a valve proper mounted for bodily movement and directly actuated by a connected operating part, and adapted in its movement to accuratel regulate the quantity of air dischar ed from the there: with associated enclosing casing to the manifold of the engine.

It is a further objectof the invention to provide an improved compensating valve of the character under consideration readily applicable to manifolds of various designs and constructions, and adapted to be operated from the dash board of the car in which the engine is mounted. I

it is further contemplated by the invention to provide a valve'construction which while primarily designed to regulate an auxiliary supply of air to the manifold, may with equally satisfactory results be utilized for supplying variable quantities of gas directly to the i'nanifold for priming purposesin starting the engine.

iore particularly the invention includes a valve casing adapted to be mounted on a suitable support, as the dash board, the casing having an inlet port and a discharge outlet or conduit adapted to be connected to the intake manifold or other part of the engine, and ja bodily movable valve within the casing adapted to be actuated conveniently by fixed connection with the valve extending without the casing, thereby regulating, according. to i the position of the valve, the air or gas as the case may be emitting from said discharge conduit.

The invention also includes means whereby the valve may be effectively locked in adjusted positions against displacement under vibration, etc, which said locking characteristic is however automatically releasable underpressure when it is desired to adjust the valve.

Still other and further improvements, and novei details in the construction and arrangement of parts will be appreciated from the description to follow, when considered in connection with the accompanying drawings. which form a part hereof,

and wherein is disclosed, for the purposes of illustration, a convenient and satisfactory embodi nent of the invention, it being borne in mind in this connection thatvarious minor changes may be resorted to without departing from the spirit of the invention.

In the drawings, 7 Figure l is a plan. view of the improved device applied to" a dash board and manifold, the latter parts being broken away.

While the spring held locking means is sufficient.

While the present attachment is moreespetomain-taintheparts in fixed position at all y cially designedforthe,regulationof air to the intake manifold at the same time, without any change whatsoever it is-equally serv- 'iceable for the priming of the. engine, the
